The gear 30 is mounted on and fixed to the shank 33 of an internal knobThe shank of this knob extends through a eircular hole in the castcasing` 2l and the gear is splined to it. rflic gear has a hub 36 which.when the parts are assembled, abuls against the inside surface ol theeasing 2t and holds the parts and against relative longitudinal motion,but they are ca pablo o't rotating in the bearing` formed for the shankThe knob has a knnrled surface, by which it, is adapted to bemanipulated and it will at all times turn the operating gear with it. Itcannotbe disconnected from it after the lock set up and assembled.

The shank 38 is provided with a slot 37 e.\:tendingY in t'roin one side,and the hub 3G also has a passage dregistering with the slotl 37. thispassage beingV termed under an extension on the. hub which tits againstthe inner wall ot the easing` 2l. This slot and passage are bounded bythe walls oli the solid portions olz the hub and shank respectively andare provided for the purpose ol admitting the end oi an arm Btl. Thisarni is pivoted at l0 on the easing. and a springe' 4l always presses itinwardly toward the center ot the rotalineY elements 30 and 35. A pin l2on the rear ot the `rear 2() is adapted to engage this arm 3S) when theparts niove around to the position shown in Fig. 5 and push it outagainst the action ot the spring'. illnother pin or shoulder lil acts onit when the rear turns backward to its eXtreme. position to again pushit out. but at other times the, s'lnine` holdsl it in theI positionshown where the end l5 of the arm 39 projects through the slot Si' and.space 3S where its end bears on the large cyliinlrical surlace oi aplunger lit lt' the plunger is pushed in the end t5 will springinto thecircular groove lt-S ou the plunger 177. This prevents longitudinalinolien ot the plunger. This plunger has a shoulder at 4S and the knobis provided with a shouldered passage inside for receiving` ii. Theextreme position ol: it is shown in Fie'. 23. The end ot the bar 22%always enters a slot, in the end ol the plunger and the spring' 27always tends to push the pung'er out.

On account olt the pin ft2 and shoulder 43 the, arm 39 is pushed back atthe two es trenies of the oscillating stroke of the open.

atin; gear so that the, l'nojection l5 is e.' drawn trom position toenter the groei t that time the plunger 47 can be I in in the directionofthe arrow in l' il f and then its end which engages the of the plateE2G pushes it back a action ot the spring' 27 so that its pin SQ will bewitlnlrawn 'trom the lriroove 3l and it will be rendered imperative.Unless the knob 35 remains in one or the other extreme position the end45 immediately comes back into the |groove @t6 and holds the plunger andplate back so that the lock cannot be operated by the key. The lever 39can be displaced only by turning the knob to eX- treme position. Whenthe partsv are in that position the gear cannot bel operated troni theoutside by means of the key, but it can be operated still usual by theknob The rest ot the lock consists of a stationary cylinder 50constituting' part of the casing; and preferably integral with it and acylindrical bolt 51 rotatably mounted upon it. The casing` is providedwith a semi-circular recess for receivingthe circular bolt. This bolt isprovided witha notch at 'for receiving the hasp 'lft as shown in Fien 1.The bolt is provided on the back with a gear segment '54: meshing' withthe rear 30. In'order to lin'iit the operation of the bolt a stop isprovided by t iscontinuingr the teeth so that the surface ot the lasttooth on each side constitutes thisi'stop.

For the purpose of stillvfinlore securely holding the door. l haveduplicated the bolt 5l by providingone exactly like it numbered 5G, andlocated adjacent to it. lt has its gear ot course on a ('lilierentportion of its` circumference, because it mesheslwith the gear 30 atl aditlerent point in the circumierence ot that. but otherwise it. is thesaine. lt. will. be understood. ot' course, that these gears are held inplace simply by securing' the rover plate 2l ou the casingv 2l.

ln the operation of the device the plunger t7 beinel in the positionshown in Fifi. 3 the operator can insert the key from the outsid. andturn the bar 253 which will turn the plate. 2G. The pin 3Q on that platewill at a certain point in its rotation engage one o't the shoulders litand turn the `rear 30 in one direetion, that is, either lock or unlockthe device. This turning ,motion is transmitted, flirectly"to the learsor bolts l and 56. and they will turn to the position shown in Fifa; l.or to that shown in'Fig. 2 as desired. Trier tothis time. the projectionlli extends into the slot tti in position to hold the plunger l? if itis pushed in. But whenerer the lock is fully locked or unhacked` the pin4t2 or shoulder' :t3 as-tlie ease may be. will engage the :nn'i3.,l 'andpush it back so that its endotiw'il'l" be drawn up out ot' reach of the`groove liti. New the plunger l-T. it already pushed in will be pushedback by `the action ot the sprii'ip; 2T and the plate will nieve with itso that the key control of the lock vwill be no longer inoperative. 1
